WIRING

Refer to equipment manufacturer’s instructions for specific system wiring information. After

wiring, see INSTALLER MENU for proper thermostat configuration. Wiring table shown are

for typical systems and describe the thermostat terminal functions.

THERMOSTAT INSTALLATION

Precautions

• Do not exceed the specification ratings.

• All wiring must conform to local and national electrical codes and ordinances.

• This control is a precision instrument, and should be handled carefully. Rough handing or

distorting components could cause the control to malfunction.

WARNING

!

Do not use on circuits exceeding specified voltage.

Higher voltage will damage control and could

cause shock or fire hazard.

Do not short out terminals on gas valve or primary

control to test. Short or incorrect wiring will burn

out thermostat and could cause personal injury

and/or property damage.

CAUTION

!

To prevent electrical shock and/or equipment

damage, disconnect electrical power to system,

at main fuse or circuit breaker box,until

installation is complete.
